" Be'it known that I, JOHN D.'OBR1EN, a citizen of the United States of America, and a resident of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Machines for Weaving Sheet-Lathi'ng, of which the following is a This invention relates to loom'mechanisms for Weaving shcet-lathing for building plasterers use, and more especially to the type of such mechanisms which constitutes the subject-matter of my prior patent, No. 765,191, dated July 19, 1904; and the present improvement has for its object to pros vide a simple and eflicient structural formation and combination of parts wherewith the weaving together of the warp and weft strips composing the sheet-lathing is attained in a continuous and automatic manner, as will hereinafter more fully appear.

I and 6 area plurality of rows of shedforming projections arranged longitudinally and inspaced relation upon the respective pe- .tions have a similar structural formation to ripheries-of the drums aforesaid with the projections on one drum or roller intermeshing with the rojections onthe other drum or roller, as s own.

the shedeforming projections of my prior patent aforesaid and involve features asjfollows: 7 represents rectangular projectionszarranged in rows alongthe oppdsed peripheries of the carrying-drums l and 2. Such projections are of a width" slightljy greater than the width of the warp-strips 8 of the lathing-sheet and are separated by intervening recesses each of which has a width some- 3 what greater thanvthat of the aforesaid pro,- jections, so as to permit of the free movement of the projections of one row in the recesses of the row in apposition, as illustrated more particularly in Figs. 5 and 6. Each row of projections 7 will also have an alternated or staggered arrangement with relation to the series of such'projections on'the next adjacent rowin both a longitudinal-and transverse direction in the machine and so that with the movement of the two series of projections in their circular paths the series ofinterposed warp-strips 8 will have a sinuous form imparted to each strip of the series and with the sinuosity of one strip alternated or staggered with relation to the sinuosity of the' adjacent strip or strips -to enable the transverse weft-strips of the sheet-lathing being ushed into position between the war -strips in the act of forming an interlaced athingjsheet with the present mechanism.

10 represents alined recesses or channels -formed centrally in the series of projections 7, as in my former patented construction.

Such recesses extend longitudinally of the I shed-forming projections and form ways for the passage and'guidance of the weft-strips 9. in the insertion of the same into interlaced position between the warp-strips 8, as above p set forth.

11 is a stationary, hop er arranged back of the carrying-drums w1t its bottom in line with the horizontal line of division between said drums. Such-hop er is adapted to contain the required num er of piles of warpstrips 8, whlch are held in proper separated relation by series of transversely-arranged temple-pins 12,- attaohed to the bottom of said hopper.

13 1s a. stationary hopper arranged'trans- .versely of the maclunewith its bottom in' line i with the line of division between the carr ing-drums 1 and 2- and also inline with t e .5. aforesaid recesses or channels l flof the pair:

of shed-forming projections that are in a uch hopper is adapted to contain a pile of weftmittent 'or step-by-step strips 9, the lowermost ones of which are successively fed into the aforesaid channels in a continued operation of the mechanism, as hereinafter more fully set forth.

14 is the driving-shaft of the machine, re ceiving rotation from any suitable power source and provided with the usual ulleys, clutches, and other ordinarycontrol ing appliances. 15 is a crank-disk carried on one end of said shaft and provided with a pawl 16, adapted to receive a reciprocating movement from said crank-disk-and to act as an operating dog or pawl in imparting an interrotation to the drums carryin the series of shed-forming projections, as, ereinafter set forth. 17 is a ratchet-disk secured to the carrying-shaft of one of the aforesaid carrying-drums and prorangement is such that with each reciproca vided with ratchet-teeth equal in number to the series of rows of shed-forming projections carried by the drum to the shaft of which said ratchet-disk is fixed. Such ratchet disk receives intermittent rotation from the reciprocating'pawl 16 aforesaid, and the artion of the pawl 16 the carrying-drums will be moved in their circular path a distance sufiicient to bring a succeeding row of shedformingprojections into the position just occupied by'a preceding row of'shed-forming projectionsj The scope of this part of the present invention embraces the substitution for the above-described mechanism of any other usual'andsuitable mechanism for im parting the described intermittent rotary motion to the carrying-drums from a driving-shaft having constant rotation. 18 is a crankrdisk carried at theother end of the ,to, moving in the bottom portion of the weftdriving-shaft l4 and provided with a pitman or link 19, having operative engagement with a reciprocating'slide, by which the weftstrips 9 are pushed from the hopper 13' into place between the rows of shed-forming projections in apposition and between the warpstrips 8 "in the sinuous condition imposed thereon by the said projections.

20 is the reciprocating slide, above referred s trip hopper 13 and having a forward ledge 21, adapted to engage behind the rear end of -the lowermost weft-strip in said hopper, so

that in a forward movement of said slide such weft-strip will be, ushedinto place between warp-strips, as a ove described.

j 22 is a bell-crank lever, one arm of which is operatively connected to the slide 20 by a radius-link 23, while the other arm of said lever is operatively connected to the pitman 19 of the crank-disk 18, before described and as illustrated in Fig. 3.

' 24 is a crank-pin carried on one side of one 1 of the connecting gear-wheels 4v of the carrvledge 26, adapted to engage behind the rear 7.5

ends of the lowermost of the piles of warpstrips in said he )per, so that in a forward movement of sai slide the lowermost series of the warp-strips will be pushed forward into the circular path of the shed-forming projections to be engaged thereby.

27 is one of several toothed racks on the under side of the feed-slide 25, and 28 is one of several sectors carried by a shaft 29, journaled on the main frame, such sectors be- 111g in operative engagement with said racks, as illustrated in Fig. 1.

30 is a crank-arm carried by the shaft 29 and operatively connected by a itman or link 31 with the crank-pin 24, )efore described.

32 is an elongated slot forming one of the connecting-eyes of the pitnian 31 aforesaid and adapted to permit a period of rest of the reciprocating slide 25 preceding the forward and backward movements of the same.

The particular mechanism shown in the drawings is adapted to produce a sheet of lathing of a predetermined size with one revolution of the series of shed-forming projections, and the period of rest above referred to in the reciprocating movement of the feeding-slide 25 is equal in extent to one period ion of movement of a row of the shed-forming projections in their circular path, so that a gap equal in extent to the distance between ad acent rows of said projections will be produced between the rear end of the sheet of lathing just finished and the forward end of the succeeding sheet of lathing in the continued operation of the machine.

The time arrangement or periodicity of the different mechanisms with relation to each other is as follows: The feeding-slide 25 is so timed as to feed the series of warp-strips into the circular patlr of the shed-forl'ning projection's while such projections are receiving an intermittent forward step and immediately subsequent to the discharge of a finished sheet oflathing from between the series of said projections. The feeding-slide 20 is so timed as to feed a weft-strip into an inter-- laced position, while the shed-forming )rojections are in a condition of rest prcce ing an intermittent forward movement in their circular aths.

Having thus fully described my said invention, what 1 claim as new, and desire to secure by Letters Patent, is-
